No storage left on IPhone 12

I would ignore that because this system data will make room when you need more space on your iPhone.

On an iPhone, the term "Other System data" refers to a category of storage that includes various types of system-related files and data that don't fit into specific categories like apps, media, or documents. Some of It represents data that is necessary for the functioning of the device but doesn't fall into easily identifiable categories.

"Other System data" can include things such as system files, cache files, logs, system updates, diagnostic data, temporary files, and more. It's a catch-all category that encompasses a wide range of data used by the operating system and built-in apps.

Sometimes, the "Other System data" category can take up a significant amount of storage space on your iPhone, and it's not clear to me what specific files or data it comprises. If you notice that your iPhone's storage is almost full and the "Other System data" is occupying a large portion of it then...

• Restart the device. That's it.

If the above does not resolve the issue then...

You may --> Clear Other storage on your iPhone or iPad - Apple Support (IN)

Tap on System Data it will take you to "Other System Data"

Now the question is what is the "Other System Data" storage. Read on...

• Other System Data: Non-removable mobile assets, like Siri voices, fonts, dictionaries, non-removable logs and caches, Spotlight index, and system data, such as Keychain and CloudKit Database. Cached files can't be deleted by the system.
• System: Space taken by the operating system. This can vary based on your device and model.

About cached files in "Other System Data"

Finder and iTunes categorize cached music, videos, and photos as Other instead of actual songs, videos, or photos. Cached files are created when you stream or view content like music, videos, and photos. When you stream music or video, that content is stored as cached files on your device so you can quickly access it again.

Your device automatically removes cached files and temporary files when your device needs more space.

If storage on your device differs from what you see in Finder or iTunes

Since Finder and iTunes categorize cached files as Other, reported usage for Music or Videos might differ. To view usage on your device, go to Settings > General > [Device] Storage.

If you want to delete the cached files from your device

Your device automatically deletes cached files and temporary files when it needs more space. You don't need to delete them yourself.

To clear storage on your iPad, you can follow these steps:

1. Go to "Settings" on your iPad and tap on "General" > "iPad Storage." This will show you a breakdown of the storage used by different apps and data on your device.
2. 
3. Scroll down to the list of installed apps and review which ones you don't use frequently. Tap on an app and select "Offload App." This will remove the app from your device while keeping its data intact. You can always reinstall the app later if needed.
4. Go through the list of apps and delete the ones you no longer need. To delete an app, tap on it and select "Delete App." Additionally, you can delete other types of data such as photos, videos, messages, and unused files to free up space.
5. 
6. If your Photos app takes up a significant amount of space, you can enable iCloud Photos to store your photos and videos in the cloud and keep optimized versions on your device. Go to "Settings" > "[Your Name]" > "iCloud" > "Photos" and enable "iCloud Photos." --> Manage your photo and video storage - Apple Support
7. If you use Safari as your web browser, you can clear its cache to free up storage. Go to "Settings" > "Safari" > "Clear History and Website Data." Please see the pic below which is self-explanatory
8. 
9. Messages and attachments can take up a substantial amount of storage. Open the Messages app and delete unnecessary conversations or individual messages. You can also enable the option to automatically delete messages after a certain period. Go to "Settings" > "Messages" > "Keep Messages" and select an appropriate duration. Deleting attachments to messages may also help
10. 
11. If you have music, movies, or TV shows downloaded on your device that you no longer need offline access to, you can remove them to save space. Open the respective app (e.g., Music or TV), find the content, and delete it.
12. Consider reviewing other apps and data that may be taking up storage space, such as documents, downloads, and podcasts. Delete unnecessary files or manage them accordingly.
13. After performing the above steps, it's good practice to restart

My system data takes up 26.7 gigabytes. Inside of this, all 26.7 gigabytes are attributed to “other system data”. There is no reason that it should take up this much storage. And I can’t delete it, there is no option to even see what that 26.7 gigabytes are actually made up. How do I fix it.

That's usually a sign of some data corruption. Back up the phone then restore it from the backup. That should resolve the issue. I recommend you do this using a computer if possible.

If you can be bothered just restore it as a new iPhone and re-decide what do keep on the iPhone. It’ll also sort the amount if System Data
